Greenheck has expanded its line of mixed flow inline fans with the addition of Model EQB. According to Greenheck, the fan combines the best properties of centrifugal and vane axial fans while providing higher efficiency and lower sound levels. Model EQB’s octagonal housing is manufactured of formed galvanized steel panels coupled with a heavy-gauge steel drive frame for and durability.
Greenheck’s ICD series of Insulated Control Dampers have earned AMCA’s new certified rating of Energy Efficiency. This new test method, which is found in ANSI/AMCA standard 500D-12, assigns a damper a Thermal Efficiency Ratio (E) by comparing its thermal performance with the thermal performance of a standard reference damper.
